A Japanese venture company, Genepax, has unveiled a car on that runs on water. All it requires is a litre of water. In fact, any kind of water to be exact, whether its river, rain, sea water, or even Japanese tea. Its an electric powered car that runs solely on hydrogen dioxide.

lol, didn't even noticed it was wrong
HO2 would probably work too ... it's an unstable binding so there's probably lots of energy to be won from it (like H202, also very unstable and almost immediatly boils when MgO2 is added ) .
